Orange Spain has announced the acquisition of Simyo, a mobile virtual network operator (MVNO) which runs on Orange Spain’s network. The financial terms of this deal have not been disclosed.

With this acquisition, France Télécom, Orange’s parent company, reports that Simyo “will continue to operate as an MVNO under its own brand and will remain hosted on Orange Spain’s network.” France Télécom believes that this acquisition “reinforces Orange’s commitment in Spain and strengthens its position in the Spanish mobile market.”

France Télécom was careful to note that this change will not impact Simyo customers, and they will be able to “keep their current tariffs and service conditions.”

As of September 2012, Orange’s total mobile customer base in Spain has grown beyond 12 million subscribers. Previously Orange Spain was known as Amena, before it was purchased in 2005.

Recently, Orange invested in Lookout, a mobile security firm.
